1. PHENONMENON OF RUSTING
Rust is the common name for a very common
compound, iron oxide. Iron oxide, the chemical Fe2O3, is common because iron
combines very readily with oxygen.
Iron (or steel) rusting is an example of corrosion -- an electrochemical process
involving an anode (a piece of metal that readily gives up electrons), an
electrolyte (a liquid that helps electrons move) and a cathode (a piece of
metal that readily accepts electrons). When a piece of metal corrodes, the
electrolyte helps provide oxygen to the anode. As oxygen combines with the
metal, electrons are liberated. When they flow through the electrolyte to the
cathode, the metal of the anode disappears,
swept away by the electrical flow or converted into metal cations in a form
such as rust.
For iron to become iron oxide, three things are required: iron, water and oxygen.
Here's what happens when the three get together: When a drop
of water hits an iron object, two things begin to happen almost immediately.
First, the water, a good electrolyte, combines with carbon dioxide in the air
to form a weak carbonic acid, an even better electrolyte. As the acid is formed
and the iron dissolved, some of the water will begin to break down into its
component pieces -- hydrogen and oxygen. The free oxygen and dissolved iron
bond into iron oxide, in the process freeing electrons. The electrons liberated
from the anode portion of the iron flow to the cathode, which may be a piece of
a metal less electrically reactive than iron, or another point on the piece of
iron itself.
The chemical compounds found in liquids like acid rain, seawater and the
salt-loaded spray from snow-belt roads make them better electrolytes than pure
water, allowing their presence to speed the process of rusting on iron and
other forms of corrosion on other metals.

HOW TO SALVAGE RUSTED
PARTS AND PREVENT FURTHAR RUSTING
Application of Water based polymer which reacts with rust
to form a passive layer which prevents rusting.
SALVAGING RUST consists
of two aspects.

||
APPLICATION
· Remove as far as
possible the flaky and loose rust, old paint by the use a wire brush. The
loose particles on the surface are then removed by the air wash or water
wash.. Grease and oil are removed by a detergent wash followed by a water
wash. Do not remove all traces of rust since it can be converted.
· Transfer a small
portion of Rust converter in a non-metallic container. After use do not pour
back the unused portion to the original container, this will prevent
contamination of the product.
· Anagha Salvage Rust is an under coat and
accepts all types of Top Coats like enamel, epoxy, polyurethane, polyester
etc.

3 HOW TO PROTECT METAL SURFACE FROM RUSTING
Proactive approach to
ensure the phenomenon of rusting is eliminated. Application of Water based
emulsion which is hydrophobic, protects against moisture and environment.
Anagha
Stop Rust contains
low particle size Polymer which helps in fast film formation. This film
is highly hydrophobic and does not allow air and moisture to pass, thereby
stops iron from rusting and metals from oxidation.
APPLICATION:
·CLEANING: Wash the surface free of loose
particles dust, oil, grease, etc., with the help of wire brush, water
and light detergent
·COATING: After the surface is dry apply
one coat of Stop Rust, allow it
to dry. It dries in 15 minutes in summer and 45 minutes in winter. After
the first coat is dry apply the second coat of Stop Rust. Allow this coat to dry
completely in 30 minutes. This completes the application procedure.
